I started a new playthrough of the Director's Cut. This time I'm playing on ranger difficulty and experiencing very different results with weaponsmithing.
During my first playthrough, early in the game, 9 of 10 times I'd get weapon parts, which was my biggest income. It wasn't until reaching California and reaching a higher skill that I got more mods.
So far during my second playthrough, it's the other way around. I kept getting sturdy mags instead of parts and now as a result I hardly have any scrap. However, after reaching the Rail Nomad Camp and getting Makarovs from pretty much every junkie foe in the area, I suddenly start getting parts again with only the occasional mod. This is without adding any points to my skill.
I guess it could have something to do with the higher difficulty setting, but the odds that I've been presented with when stripping for parts haven't matched the outcome. I can't have been that lucky/unlucky.
Also find it odd that in everyone in RNC suddenly drop their weapons when they're otherwise so scarce. I guess they must've forgotten to change it for DC in this particular area.
